To get the 2-in-1 script by @IO_Nox configured to work with the Loud mod & FAF, there are at least a couple ways to go:
If you haven't already done so, go into the Tools of the SCFA_Updater.exe (aka LOUD Updater) & Create Shortcuts. You should see a couple new shortcuts, one of which is called LOUD Forged Alliance. In the script, change the reference for
pathOrLinkGame to point to the new LOUD Forged Alliance shortcut. The shortcut already has the parameters it needs for running Loud in the target.
If you don't want to use a shortcut reference, you can enter the parameters directly in the script:
pathOrLinkGame := "F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\bin\SupremeCommander.exe /log ""F:\SteamLibrary\steamapps\common\Supreme Commander Forged Alliance\LOUD\bin\Loud.log"" /init ""..\LOUD\bin\LoudDataPath.lua"""
The paths above are for my SCFA & Loud installs, so make sure you change them as needed for yours. Also note that for the log parameter, the full path is need instead of just using
..\LOUD like for the init parameter.
The code for the FAF side of things remains unchanged.
With the changes complete, to play Loud, just open the script file normally. To play FAF, either open the Run command (Windows+R) & enter the script's file path followed by an
faf parameter or copy/paste the script file & rename it beginning with FAF.
